IMPROVEMENT IN DEVICE FOR ELEVATING ICE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY LITTLE, of Middletown, in the county ofOrange, and State of New York, have invented a new and improved Devicefor Elevating Ice; and that the following description, taken inconnection with the accompanying drawings hereinafter referred to,formsa full and exact specification of the same, wherein I have setforth the nature and principles of my said improvements, by which myinvention may be distinguished from all others of a similar class,together with such parts as I claim, and desire to have secured to me byLetters Patent.

This invention relates. to a new and improved contrivance forelevatingice from the river, pond, or lake where it is cut, into theice-house contiguous thereto.

The invention consists of a rotating vertical screw elevator and astationary or fixed bearing, arranged to operate in the mannersubstantially as hereinafter fully shown and described. In theaccompanying sheet of drawings Figure 1 is an elevation of my invention.

Figure 2, a horizontal section of the same, taken in the line a: x, fig.1.

Similar letters of reference indicate like parts. I

A represents an upright frame, constructed in' any suitable manner tosupport a vertical shaft, B, whicl.

has horizontal radial arms, 0, attached in a spiral line. To the outer.ends of these arms there is attached a rim, D, which forms a spiral wayor track all around the shaft B, extending from its lower to its upperend,

the spiral form of the rim or way being of course due to the spiralpositiouof the arms C. necessary or desired, two rims or ways D may beattached to the arms 0, one being within the other that is to say, ,the

second one attached to the arms 0 at a short distance from their ends. Erepresentsa'bearing composed of an upright rod or bar in the framing A ashort distance from the rim or way D.

This device is put up in such a maner that the lower end of the way 1)will be in the water, a space being kept free of ice to admit of thelower part of the screw rotating therein, The blocks of ice as they arecut are placed on the rim or way D behind thebearing E, and, as theshaft 13 is rotated, the ice will be elevated by the spiral rim, thebearing E preventing the ice from turning with the rim or way. As theblocks of ice are raised above the bearing E they pass into a chute,which conducts them into the ice-house. The lower end of the spiral rimor way is placed in the watcr,-or as low as possible, in order tofacilitate the placing of the blocks of ice on the rim or way Inpractice, I design to have the bearing E constructed in sections, sothat its height may bevaried to suit the height the blocks of ice are tobe raised, for it will be understood that icehouses are provided with aseries of doors, one above the other, the chute being adjusted todifferent doors as the filling of the house progresses, commencing withthe lowermost one. This is necessary in order to prevent the blocks ofice being broken by falling fromvtoo great a height, which would be thecase were the ice discharged into or through an uppermost door at thecommencement of the operation; The elevator may be turned by horsepower,a single horse being sufficient for the purpose, and the power appliedin any suitable manner; or it may be operated by steam or water-power.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent-'- The rotatory screw elevator, in combination withthe bearing, arranged to operate in the manner substantially as'and forthe purpose set forth.
